MOSCOW- Russia's oil export duty will decline to $42.2 per tonne from Nov. 1 from $45.4 in October, following a fall in oil prices, the finance ministry said on Thursday.

The level of the duty is calculated by the finance ministry and is based on the monitoring of seaborne Urals  crude oil prices.

The ministry made its calculations for the November export duty from prices recorded between Sept. 15 and Oct. 14.

The discounted rate for crude produced at newer fields in eastern Siberia, fields operated by Lukoil in the Caspian Sea and Gazprom Neft's Prirazlomnoye offshore Arctic field.
